- the wind power from the Z Blades may or may not be responsible for the rotation speed unless sustained winds of 20 MPH or more are available. Should the wind suddenly drop to zero the Electro Magnetic Pulse Drive system will continue to accelerate the rotation of the Wind-Mag Generator.
- stepper motor may also be thought of as a cross between a DC electric motor and a rotary solenoid. As each coil is energized in turn, the rotor aligns itself with the magnetic field produced by the energized field winding. Unlike a synchronous motor, in its application, the stepper motor may not rotate continuously; instead, it “steps” meaning it starts and then quickly stops again.
Abstract
Description
- The invention has particular application to methods and apparatus for harvesting wind energy to produce electric power. More particularly, the apparatus that typically has a vertical axis of rotation and a rotor that is generally cylindrical.
- The market for such products includes ships at sea and in port. Large sizes of such apparatus are suitable for utility companies and are suitable to be mounted on a base in close proximity to established power transmission towers. Such installations utilize the same land and access roads with direct connection to their established power line grid and thus eliminating the cost of building new grid infrastructure from wind driven areas. Mid sizes of such apparatus are suitable for hospitals, schools, offices and other commercial buildings where they may be connected to the buildings own power grid. Smaller sizes of such apparatus are suitable for ships at sea and in port, private homes. Portable units are suitable for the military operating in hostile environments and scientists operating in isolated hard to reach communities where fuel is delivery is difficult.
- Worldwide interest in renewable energy options has given rise to a rash of new wind turbine designs. Some of the most recent models on the market are vertical axis wind turbines (VAWTs) that are quiet, efficient, economical and perfect for residential energy production, especially in urban environments.
- The prior art includes two vertical axis wind turbine (VAWT) designs. One form of the Savonius rotor can be visualized as a 55-gallon drum and cut it in half along a plane passing through the geometric axis of the drum which bisects the drum. Then the two halves of the drum are mounted on a shaft that rotates in a manner similar to an anemometer.
- Another form is the Darrieus apparatus that resembles an egg beater. Essentially, it has two vertically oriented blades revolving around a vertical shaft. The blades are airfoils. These airfoils, like airplane wings, have a flat side and a curved side. The result of air passing over the two sides is a force known as lift. Because the airfoils are secured to a hub, which in turn is attached to a generator shaft the air passing over the airfoil shaped blades produces rotational movement which spins the generator.
- It is an object of the present invention to provide apparatus and a method suitable for installation and use in a variety of worldwide locations including but not limited to North America, South America, the African continent, Europe, United Kingdom, Australia, Russia, China, and all Asian and Arab countries. As a standalone power option, or as a supplemental power source to aid old over worked power generation plants that are reportedly failing on a daily basis.
- Another object of the present invention to provide an apparatus and a method suitable both for large scale power grids as well as substantially independent power consumers such as remote Islands and isolated interiors of large continents.

FIGS. 1 , 2 and 5 astationary platform 20 supports the rest of the apparatus. Fixed to thestationary platform 20 is aplatform pipe 37. Theplatform pipe 37 is an axis or spindle for the rotating portions of the apparatus. Thestationary platform 20 includes a circular area (not shown) centered on the geometric centerline of theplatform pipe 37. The circular area includes a plurality of elongated grooves (not shown) disposed in aligned relationship with respective radial lines from the geometric center line of theplatform pipe 37. The grooves are disposed at equal angular positions about the geometric centerline of the apparatus and are dimensioned and configured for receivingrespective rollers 18. Therollers 18 are roller bearings supporting the rotating structure of the apparatus including thepower ring assembly 13. - The rotating parts of the apparatus include a plurality of Z
shaped blades 1 mounted uniformly about the circumference of thepower ring base 19 as best seen inFIGS. 1 and 5 . Thepower ring base 19 is an annular plate shaped member having a circular opening therein that is concentric with respect to the outside circular edge thereof. The circular outer contour and the circular opening are concentric and have the geometric centers thereof coincident with the geometric centerline of theplatform pipe 37 in the preferred embodiment. The rollers 18 (carried in the platform 20) also engage grooves (not shown) disposed in the bottom of thepower ring base 19 and support thepower ring base 19 in a manner to allow easy rotational movement of thepower ring base 19. (Alternate embodiments may use magnetic levitation to support thepower ring base 19.) - The
power ring base 19 is part of cylindricalpower ring assembly 13. The axis of thepower ring assembly 13 is coincident with the axis of theplatform pipe 37. As best seen inFIG. 2 the upper axial extremity of the center pipe 15 (that is part of the power ring assembly 13) is provided with alip 13A extending radially away from the geometric center line of the power ring. As best seen inFIG. 1 thepower ring assembly 13 is concentric with theplatform pipe 37 and of larger diameter than theplatform pipe 37. A plurality ofroller assemblies 17 are mounted on thepower ring base 19 as best seen inFIGS. 1 , 2 and 4. Eachroller assembly 17 includes aroller wheel 9. Thepower ring assembly 13 includes eightopenings 16 disposed at equal angular positions about the circumference of thecenter pipe 15. Theopenings 16 are provided to allow access of the respective highspeed roller wheels 9 of therespective roller assemblies 17 through thepower ring assembly 13 so that theroller wheels 9 engage the outer wall of thestationary platform pipe 37 to enable easy rotation of thepower ring assembly 13, (including thepower ring base 19, as well as the roller assemblies 17) about theplatform pipe 37. Accordingly, eachroller wheel 9 extends through one of therespective openings 16 in the center pipe 15 (that is also a part of the power ring assembly 13) to engage the outer face of theplatform pipe 37. - Mounted on the
platform 20 are fourgenerators 10 as best seen inFIG. 3 . Eachgenerator 10 includes adrive wheel 23. Eachgenerator 10 is supported bytriangular brackets 27, 30 that are fixed to theplatform 20 and positioned for engagement between therespective drive wheels 23 and alip 13A of thepower ring assembly 13. Preferred embodiments of the present invention rely on frictional engagement between thelip 13A and therespective drive wheels 23. In illustrated preferred embodiment there are four generators successfully positioned at 90° about the circular extent of thelip 13A. Other embodiments of the present invention may utilize a bevel gear interface for the drive wheels. The output of therespective generators 10 is directed sequentially to an outgoing generatedenergy junction box 35 and outgoing power cable and plugoutlet 36. - A preferred embodiment of the present invention includes a 100
w 12volt alternator 21 that is also supported on theplatform 20 in the same general manner as thegenerators 10. Also on the same general manner as thegenerators 10, thealternator 21 includes adrive wheel 22 that engages thelip 13A. Unlike thegenerators 10, thedrive wheel 22 engages thelip 13A at all times. In other words, thedrive wheel 22 is not raised and lowered during the operating process in the general manner as that used for thegenerators 10. The output of thealternator 21 is supplied to aregulator 34 that includes, a 12 V DC regulator sequentially connected to a mag pulse width modulator. The output of thatregulator 34 is fed by a cable to a magpulse distribution box 33 and then into apulse distribution harness 32 and then into respective positiveelectromagnetic assemblies 25. Theelectromagnet assemblies 25 cooperate with respectivepermanent magnets 24 attached to thecenter pipe 15 to be described hereafter. Some embodiments include respective light emitting diodes associated with eachelectromagnet assembly 25 to provide a visual display for each electromagnet assembly to indicate when theelectromagnet assembly 25 is energized. - As best seen in
FIGS. 1 and 5 , threesupports 11 are welded at 60° angles to thepower ring base 19 at the lower axial extremity thereof and to asupport plate 12 at the upper axial extremities thereof. In a preferred embodiment of the invention thesupports 11 are manufactured from square tubing. As best seen inFIG. 5 support plate 12 is welded to asupport pipe 6 that extends vertically through thedish dome 2. Aweld 36 verse thedish dome 2 thesupport pipe 6. The upper axial extremity of thesupport pipe 6 includes a lifting eye 4 for allowing a hoist (not shown) to move the entire assembly. As best shown inFIG. 5 , a centrifugal ball assembly 7 (that includes three balls 8) is fixed to thesupport pipe 6. As the rotor revolves, thesupport pipe 6 also revolves causing theballs 8 to move up and out from thesupport pipe 6. This movement increases the inertia of the rotor and thereby causes thepower ring assembly 13 to continue rotating after rotation has once begun. - The Z-shaped
blades 1 are fixed around the periphery of thepower ring assembly 13 as best seen inFIG. 1 . As shown inFIG. 2 the lower axial extremity of eachblade 1 is fixed to thepower ring assembly 13 by a retainingangle 14. In a similar manner the upper axial extremity of eachblade 1 is fixed to thedish dome 3. - The following will describe certain aspects of the above apparatus in greater detail. The Z-shaped
blades 1 have a preferred cross-section, shown inFIG. 1 that includes a planar midsection joining to parallel planar extremities or flanges that are disposed in oblique relationship to the midsection. Theblades 1 are made from non-corrosive marine 5086 aluminum of ⅛ inch thickness by 6 feet 9¾ inches tall, 12 inch wide, plasma cut with opposed sides that are substantially elliptical section shape, stiffened and rolled with one inch wide flanges disposed at an angle of substantially one hundred degrees to the body of the blade as best shown inFIG. 1 . As shown inFIG. 1 the flanges are disposed on the longitudinal sides of each blade and are rolled in opposite directions to form a Z shaped cross section. The term “substantially elliptical section shape” will be understood to mean that opposed sides of the blades have portions of the blades that have contours that are substantially the contour of a section of an ellipse. In the preferred embodiment the contour of the intersection between (1) the respective flanges extending from the main body of the blade and (2) the main body of the blade is generally elliptical as best seen inFIG. 5 . - The side of the
blades 1, facing the wind, have a matte finish in order to increase the capture of the energy in the wind that impacts theblade 1. More specifically, a gloss finish would deflect the energy of the wind and thus is less desirable - A preferred embodiment of the present invention will include various more specific aspect. For example, the bottom of each
blade 1 is secured by two bolts through analuminum Retaining angle 14 welded to the ⅝ inch×6 ft diameterpower ring base 19. The top of theblades 1 are secured by two bolts through 5086 ⅛ inch aluminum gussets 5 welded to the ⅛inch dish dome 2 at the same 22% angle with respect to radial lines from the geometric center of thepower ring 13 as the bottom angles. Theblades 1 are uniformly spaced from the center of thepower ring 13 as well as uniformly spaced about the periphery of thepower ring 13. - The
power ring base 19 is manufactured by starting with a 6 ft outside diameter flat circle of ⅝ inch 5086 marine aluminum sheet stock. Thepower ring base 19 is an annular plate with a inner bore or hole to which is attached acenter pipe 15 having a length of 12 inches. Thecenter pipe 15 is 6¾ inch×⅜ inch 5086 aluminum pipe and is welded to the edge of the bore of thepower ring base 19. Thecenter pipe 15 has eight equally spaced 6 inch×3 inch plasma cut roller wheel access holes 16. Theholes 16 accommodate eight equally spaced about the circumference of high speed self lubricatingheavy duty 6 inch×2inch roller wheels 9. Theseroller wheels 9 are held in place by eight adjustableroller wheel assemblies 17 that are welded to thepower ring base 19. - Disposed on the top of the
center pipe 15 is a 3 inch×2 inch×⅜ inch rolled 5086 aluminum flange orlip 13A having a 2 inch height and the 3 inch horizontal facing. Thelip 13A is welded flush with the top of thecenter pipe 15. Thelip 13A engages thealternator wheel 22 and the fourgenerator drive wheels 23. Disposed 2¾ inches down from the top of thecenter pipe 15 on the inner bore thereof (opposite side of the 2×3×⅜ angle) are 49rare earth magnets 24 attached to thecenter pipe 15. - The power ring assembly has three equally spaced 2 inch×2 inch×¼ inch square tubing centrifuge supports 11. These supports 11 are welded to the ⅝ inch thick
power ring base 19, rolled to meet in the center of thepower ring assembly 13 at apoint 36 inches above thepower base 19 where they are welded to a ½ inch×6inches support plate 12. Thesupport pipe 6 is welded in the middle of thesupport plate 12 and extends vertically at the center of thepower ring assembly 13 to aweld 3 at the top of the 10 inch deep×4 ftwide dish dome 2. On the top of thesupport pipe 6 is a welded a ⅝ inch eye bolt 4. Welded to thesupport pipe 6 at 18 inches high from the ½ inch×6inch support plate 12, are three ⅛ 1×½×1×6 inch long U channel hanger supports for attachment by bolts and locking nuts for the centrifuge rod and balls andrestrainers 7 that are welded at the same center line as the 2×2×¼ inch square tubing centrifuge supports 11. - A feature of embodiments of the invention is the alternator and electro magnetic pulse
drive generator platform 20. This consists of the following: A 5086 marine aluminum plate measuring 6′ ft×6′ ft square×1 inchthick platform 20. Centered on theplatform 20 is a 4 feet diameter spin area which is located below thepower ring assembly 13. The spin area has eight uniformly spaced plasma cut center line slots of the size of 2×8 inch. 2 inches from both inner and outer edge of the spin area. Disposed within each of these slots is a high speed rollers of the size of 1½ inch×7½ 18 retained by screws through the mounting brackets on each end. - A circle having a diameter of 2 ft 11¼ inches centered on the generating
platform 20 defines the location of the circumference of theplatform pipe 37 having a height of 6 inches with a thickness of ½ inch and manufactured of 5086 marine aluminum. Theplatform pipe 37 is welded on the inside bottom to theplatform 20. Welded to the inside of thisplatform pipe 37 and the bottom of the generator platform are 49 equally spaced 5×4×⅛ inch Mag pulse laserdrive mounting brackets 26. From 1¼ inches down from the top of thisplatform pipe 37 are 49 equally spaced Plasma cut 3 inch vertical by 1 inch horizontal access holes to accommodate theelectromagnet coil assemblies 25. Theelectromagnetic coil assemblies 25 cooperate withpermanent magnets 24 mounted on thecenter pipe 15. Thus, the construction is consistent with that of a conventional stepper motor to be described hereafter. The apparatus also includesbrackets 29 each supporting a tension snubber 28. Each tension snubber 28 is a 12 v electronic jack maintains frictional engagement between thealternator drive wheel 22 and thepower ring lip 13A. Each snubber 28 is welded to the center line of one the fourrespective alternators 21. Two 3/16 inch 5086 marine aluminum alternator mounting gussets or brackets 27 are welded to thegenerator platform 20. The fouralternators 21 are equally spaced on theplatform 20 and held in place by four gravity tip generator brackets of ½ inch 5086marine aluminum brackets 30 welded to the generator platform. Disposed in the middle of the generatingplatform 20 is a 6 inch round plasma cut access hole for the outgoing generated power through a outgoing power cable and plugoutlet 36. - After the generator has been mounted in the appropriate location, the stops will be taken out and the
generators Z blades 1 will be free to react to the area breezes' and winds. As thepower ring assembly 13 starts to spin, thecentrifugal ball assembly 7 comes into play to add inertia to the spinning with its three spinning 5lbs centrifuge balls 8. At this point the 100 watt 12V alternator 21 starts to spin on thepower ring assembly 13. This creates voltage output from thealternator 21 to the voltage regulator located inside the pulse width modulator micro processor andvoltage regulator 34. Electric pulses then enter the magneticpulse distributor box 33 causing pulses in thepulse distributor harness 32. These electronic pulses are then distributed from the harness by individual wire feeds 31 and then to the forty nine equally spaced equally spacedelectromagnet assemblies 25 that now creates a positive electro magnetic-pulse laser drive. Small light emitting diodes are positioned next to each of the respective magnets to indicate the sequential application of electric power. Thus, each of the respective flashing light emitting diodes indicate a respective working pulse. - The opposing rare
earth bar magnets 24. are mounted on the inside of the spinning vertical 6¾×⅜ inch 5086aluminum center pipe 15 by a plastic retainer that covers the positive side of the rare earth magnets allowing the negative side to draw to the positive electro magnetic-pulse magnets without the drag of the repulsive magnetic flux from the positive side of the rare earth magnets. - As the Z-shaped blades harness wind power to spin the
power ring assembly 13 along with thecentrifugal ball assembly 7, thealternator 21 rotating as the result of rotation of thepower ring assembly 13 starts to produce voltage, sending it through the Mag pulse drive system, causing the electro magnetic pulse drive to come into play without any outside electrical power source. As it gains speed to the equivalent of a 5 mph ambient wind a speed sensor sequentially activates the four low voltage generator tension snubbers electronic jacks 28. More specifically, as the speed sensor increases the four low drag variable speed directdrive generator wheels 10 are sequentially lowered to engage thepower ring assembly 13 to start electrical generation of 2 to 10 KW each. Some embodiments will use thecentrifugal ball assembly 7 to sense the speed of rotation. Other speed sensors may merely provide a permanent magnet that passes a cooperating coil and core to detect speed of rotation. - As the rotation speed of the
power ring assembly 13 increases it increases the power output from the fourgenerators 10. At this point the wind power from the Z Blades may or may not be responsible for the rotation speed unless sustained winds of 20 MPH or more are available. Should the wind suddenly drop to zero the Electro Magnetic Pulse Drive system will continue to accelerate the rotation of the Wind-Mag Generator. - When the rotation speed from the
power ring assembly 13 exceeds the speed corresponding to an ambient prevailingwind 20 MPH (when theZ blades 1 encounter winds over 20 MPH) speed sensors will interrupt the voltage coming from the alternator to the Mag drive system causing the Mag-Pulse Drive to temporary stop operating and the four generators to drag the speed of the power ring down to a pre set speed comparable to the speed produced by a 20 MPH ambient wind where at this point the speed sensor will reconnect the voltage from the Alternator to the Electro Magnetic-Drive system regulating rotation speed to a maximum of corresponding to the rotational speed caused by 20 MPH ambient wind. - The operation of the
alternator 21, coils 25,rare earth magnets 24pulse distributor harness 32, magneticpulse distributor box 33, pulse width modulator micro processor andvoltage regulator 34 will be closely related to the design of stepper motors where an internal rotor containing permanent magnets or a magnetically-soft rotor with salient poles is controlled by a set of external magnets that are switched electronically. A stepper motor may also be thought of as a cross between a DC electric motor and a rotary solenoid. As each coil is energized in turn, the rotor aligns itself with the magnetic field produced by the energized field winding. Unlike a synchronous motor, in its application, the stepper motor may not rotate continuously; instead, it “steps” meaning it starts and then quickly stops again. Thus, it moves from one position to the next as field windings are energized and de-energized in sequence. Simple stepper motor drivers entirely energize or entirely de-energize the field windings, leading the rotor to “cog” to a limited number of positions. So-called quartz analog wristwatches contain the smallest commonplace stepping motors; they have one coil, draw very little power, and have a permanent-magnet rotor. The same kind of motor drives battery-powered quartz clocks. - Although the description expressly refers to materials such as 5086 aluminum, those skilled in the art will also alternative materials including but not limited to stainless steel and composites depending on environmental requirements, price points and end user requirements.
